Description

  The present invention relates to a switch member used for electrical switching and a switch device using the switch member.

  As a switch device, a device using a plate-like switch member has been proposed, and the switch member includes a connection terminal portion that is electrically connected to the outside at one end portion of one metal plate. In addition, a contact is provided at the other end (see Patent Document 1).

JP 2002-279879 A

  In the switch member described in Patent Document 1, it is required that the portion where the contact portion is provided has elasticity. For this reason, since a thin metal plate is used as the switch member, the connection terminal portion also has elasticity, and there is a problem that the electrical connection method at the connection terminal portion is limited. Thus, in the conventional switch member, the strength increase of the connection terminal portion and the like and the securing of the elasticity at the portion where the contact portion is provided are in a trade-off relationship that if one is satisfied, the other is troubled. .

  Therefore, it is possible to use metal plates that are partially different in thickness, with the thick part as the part that is held by the connecting terminal part or case where electrical connection is made, and the thin part as the part where the contact part is provided. Though conceivable, such a metal plate is expensive because it requires special processing.

  In view of the above problems, an object of the present invention is to provide a switch member capable of forming an elastic plate portion having appropriate elasticity and a connection terminal portion having high strength with a metal plate having a constant thickness, and It is providing the switch apparatus using the said switch member.

  The switch member to which the present invention is applied has a metal plate partially folded, a connection terminal portion is constituted by the folded portion of the metal plate, and an elastic plate portion is constituted by a single portion of the metal plate. For this reason, even when a metal plate having a constant thickness is used, an elastic plate portion having appropriate elasticity and a connection terminal portion having high strength can be formed.

  In the present invention, it is preferable that one end portion in the longitudinal direction of the metal plate is folded toward the other end portion. According to this configuration, the switch member can be easily manufactured as compared with a configuration in which the metal plate is folded in the width direction. Further, since the end portion of the connection terminal portion is formed of a bent portion of the folded portion, burrs, edges, and the like are unlikely to occur. Therefore, it is difficult for hooking or the like to occur when the connector is coupled to the connection terminal portion.

  In the present invention, it is preferable that two of the folded portions are connected at the end opposite to the elastic plate portion. According to this configuration, burrs, edges, and the like are unlikely to occur at the end of the folded portion opposite to the elastic plate portion. Therefore, it is difficult for hooking or the like to occur when the connector is coupled to the connection terminal portion.

  In the present invention, at the end of the folded portion opposite to the elastic plate portion, the width of the bent portion bent at the end is smaller than the width of the portion adjacent to the bent portion. It is preferable. According to such a configuration, burrs and the like are unlikely to occur at the bent portion.

  In this invention, it is preferable to have the coupling member which couple | bonds the parts which mutually overlap in the said folding part among the said metal plates. According to such a configuration, the folded portion can be prevented from opening.

  In this invention, it is preferable that the said coupling member is provided in the edge part by the side of the said elastic board part among the said folding parts. According to this structure, it can prevent reliably that the folded part opens.

  In the present invention, the coupling member is preferably a resin portion formed by insert molding with the metal plate.

  In the present invention, it is preferable that a plurality of the metal plates are provided, and the plurality of metal plates are joined by the resin portion. According to this configuration, a plurality of metal plates can be handled integrally. Moreover, the positional accuracy between metal plates can be increased.

  In this invention, it is preferable that the opening part opened toward the thickness direction of the said folding part is formed in the part which overlaps with the said folding part of the said resin part on both sides of the thickness direction. According to this configuration, since the folded portion can be pressed by the mold during the insert molding, the folded portion is not opened until the insert molding is completed.

  The switch member to which the present invention is applied is used in various switch devices. In this case, it is preferable that the switch device has a holding member that holds the switch member via the folded portion. According to such a configuration, since the switch member is held at a portion having high strength, the switch member can be appropriately disposed.

  In the switch device to which the present invention is applied, when the switch member includes the coupling member, the switch device preferably includes a holding member that holds the switch member via the coupling member. According to such a configuration, since the switch member is held at a portion having high strength, the switch member can be appropriately disposed.

  The switch device to which the present invention is applied preferably has a connector coupled to the connection terminal portion. With such a configuration, the connection terminal portion is used for connector connection. However, according to the present invention, since the connection terminal portion has high strength, the connection terminal portion can endure the attachment / detachment of the connector.

  The switch member to which the present invention is applied has a metal plate partially folded, a connection terminal portion is constituted by the folded portion of the metal plate, and an elastic plate portion is constituted by a single portion of the metal plate. For this reason, even when a metal plate having a constant thickness is used, an elastic plate portion having appropriate elasticity and a connection terminal portion having high strength can be formed.

  Hereinafter, a switch member and a switch device to which the present invention is applied will be described with reference to the drawings.

(Configuration of switch device)
FIG. 1 is an exploded perspective view showing a configuration of a switch device to which the present invention is applied. FIG. 2 is a plan view showing a main part of the switch device to which the present invention is applied. The basic configuration of the switch device shown in FIGS. 1 and 2 is the same as that of the time switch described in Japanese Patent Application Laid-Open No. 2002-279879, and therefore only the outline thereof will be described in the following description.

  1 and 2, the switch device 1 is a time switch, and includes a first case 11 made of resin that houses and supports a mechanism portion, and a barrel 13 that houses a spring (not shown) serving as a drive source. It has the 2nd case 14 formed. In the switch device 1, the case 12 is configured by coupling the first case 11, the second case 14, and the bolt 120 or the like.

  A bearing hole 116 that supports the main shaft 15 is formed in the center of the first case 11. One end 150 of the main shaft 15 penetrates the bearing hole 116 and protrudes from the first case 11 to which a knob (not shown) for setting time is attached. The other end of the main shaft 15 is supported by the second case 14, and a resin main gear 17 is frictionally coupled in the vicinity of this end. For this reason, a friction clutch is formed between the main shaft 15 and the main gear 17. Note that a stop cam, a separation cam, and the like that control the stop of the operation are provided between the main gear 17 and the first case 11.

  The pinion 18 meshing with the main gear 17 has a ratchet pawl engaged with a ratchet inner tooth of a resin large gear 19 coaxial with the pinion 18 to form a one-way clutch. For this reason, when the mainspring 15 is wound and stored, the rotational force of the pinion 18 is not transmitted to the large gear 19, and when the main shaft 15 is rotated in the reverse direction by the mainspring biasing force, the rotation of the pinion 18 is rotated. The force is transmitted to the large gear 19.

  When the spring accumulating force slowly rotates the pinion 18 via the main gear 17 in the direction opposite to the direction in which the mainspring is wound, the escape wheel 22 made of resin is rotated at high speed via the speed increasing gear train 20. An anchor 24 integrated with the inertia pendulum 23 is engaged with the ratchet of the escape wheel 22. The inertia pendulum 23 is reciprocated by the rotation of the escape wheel 22 in one direction, and the speed at which the speed increasing gear train 20 and the main shaft 15 rotate in the winding direction of the mainspring is adjusted to be constant. In this way, the timer mechanism 25 is configured by the large gear 19, the speed increasing gear train 20, the escape wheel 22 and the inertia pendulum 23.

The operation cam 26 is coaxially connected to the gear 201 of the speed increasing gear train 20 with which the large gear 19 is engaged, and rotates together with the gear 201. The operation cam 26 is a multilayer cam in which four layers of cylindrical cams having different height patterns on the outer periphery are laminated in the axial direction. Such a cylindrical cam includes a first cylindrical cam pair whose phase is shifted and a second cylindrical cam pair whose phase is shifted.

  The movable contact plates 51 and 52 and the fixed contact plate 29 are fixed to the first case 11. The distal end portion of the fixed contact plate 29 is bent at a right angle in a direction crossing the movable contact plates 51 and 52 in the width direction, and two fixed contacts 291 are provided at positions facing the movable contact plates 51 and 52. Contact points 511 and 521 that can contact each of the two fixed contacts 291 are provided at the distal end portions of the movable contact plates 51 and 52.

  A connection terminal portion 290 for external connection is formed at the base end portion of the fixed contact plate 29. Connection terminal portions 510 and 520 for external connection are formed at the base end portions of the movable contact plates 51 and 52. The movable contact plates 51 and 52 extend in parallel, and the connection terminal portions 510 and 520 of the movable contact plates 51 and 52 are adjacent to each other. In this embodiment, the connector 60 is coupled to the connection terminal portions 510 and 520 when electrical connection is made to the connection terminal portions 510 and 520. The detailed configuration of the movable contact plates 51 and 52 will be described later with reference to FIG.

  The driven portion of the switch lever 30 is in sliding contact with any cylindrical cam of the operation cam 26, and the driven portion of the switch lever 31 is in sliding contact with the other cylindrical cam. The switch levers 30 and 31 have shaft holes formed in the bases fitted in lever shafts 119 provided upright in the first case 11, and rotate around the lever shaft 119 as the operation cam 26 rotates. The switch levers 30 and 31 are formed with contact plate operation portions 303 and 313. When the switch levers 30 and 31 are swung by the operation cam 26, the contact plate operation portions 303 and 313 are movable contact plates. 51 and 52 are pressed.

  Next, the operation of the switch device 1 will be briefly described. First, the main shaft 15 is rotated by a knob (not shown) operation to sufficiently wind the mainspring, and then a required time is set according to the scale while the knob is returned. At this time, the main gear 17 rotates and the main shaft 15 rotates, and the displacement angle from the original position becomes the set time limit. The main shaft 15 is driven by the mainspring within the set angle range and returns to the original position.

  In this process, the energy storing force of the mainspring rotates and drives the speed increasing gear train 20, and the main shaft 15 is driven to rotate at a constant speed in the direction opposite to the winding direction of the mainspring by the operation of the timer mechanism 25. Further, the switch levers 30 and 31 follow the operation cam 26 via the switch levers 30 and 31. As a result, the contact 511 and the fixed contact 291 switch between a state in which they are in contact with each other at a predetermined timing and a state in which they are separated, and the contact 521 and the fixed contact 292 are in a state in which they are in contact with each other at a predetermined timing. Switch to. Accordingly, the potentials of the connection terminal portions 510 and 520 are switched at a predetermined timing. Therefore, in an electric device such as a washing machine, a predetermined operation is automatically executed based on the potential change of the connection terminal portions 510 and 520.

Further, the elastic plate portion 512 is constituted by a single portion 552 of the metal plate 55.

  In this embodiment, the metal plate 55 constituting the movable contact plate 51 is folded so that one end portion in the longitudinal direction faces the other end portion. For this reason, the end portion of the connection terminal portion 520 is composed of a bent portion 555 in which two outer portions of the folded portion 550 are connected. In the metal plate 55 constituting the movable contact plate 51, a through hole 553 is formed in the folded portion 550 (connection terminal portion 510). For example, the through hole 553 is used for connecting a lead wire or the connector 60. It is used for retaining when connecting. In the movable contact plate 51, the side of the bent portion 555 is obliquely cut at the end of the folded portion 550 opposite to the elastic plate portion 512, and the width of the bent portion 555 is the bent portion 555. It is narrower than the width of the adjacent part.

  Similarly to the movable contact plate 51, the movable contact plate 52 has a structure in which the base end side of the metal plate 55 having a constant thickness is partially folded, and such a double folded portion. A connection terminal portion 520 is configured by 550. Further, the elastic plate portion 522 is constituted by a single portion 552 of the metal plate 55. In this embodiment, the metal plate 55 constituting the movable contact plate 52 is folded so that one end portion in the longitudinal direction faces the other end portion. For this reason, the end portion of the connection terminal portion 520 is composed of a bent portion 555 in which two outer portions of the folded portion 550 are connected. In the metal plate 55 constituting the movable contact plate 52, a through hole 553 is formed in the folded portion 550 (connection terminal portion 520). For example, the through hole 553 is used when connecting a lead wire or the connector 60. It is used for retaining when connecting. In the movable contact plate 52, the side of the bent portion 555 is obliquely cut at the end of the folded portion 550 opposite to the elastic plate portion 522, and the width of the bent portion 555 is the bent portion 555. It is narrower than the width of the adjacent part.

  Here, the movable contact plate 51 is provided with a coupling member 59 for coupling portions of the metal plate 55 that overlap each other in the folded portion 550, and the coupling member 59 is an elastic plate in the folded portion 550. It is provided at the end on the part 512 side. For this reason, in the movable contact plate 51, the folded portion 550 does not open. Further, the coupling member 59 also covers the movable contact plate 52 and couples the movable contact plate 51 and the movable contact plate 52. Note that the coupling member 59 also joins the overlapping portions of the folded portion 550 at the end portion on the elastic plate portion 522 side of the movable contact plate 52 even in the movable contact plate 52. For this reason, the folded portion 550 does not open in the movable contact plate 52.

  Therefore, in the switch member 50 of the present embodiment, the movable contact plate 51 and the movable contact plate 52 are integrated by the coupling member 59, and both the movable contact plate 51 and the movable contact plate 52 are configured to display the contacts 511 and 521. 1 and parallel to the fixed contact 291 side shown in FIG. In the switch member 50 of the present embodiment, the elastic plate portions 512 and 522 have a single portion 552 (elastic plate portions 512 and 522) folded over a portion 550 (connection terminal portion) in both the movable contact plate 51 and the movable contact plate 52. 510, 520), the contact points 511, 521 are bent obliquely toward the opposite side.

The coupling member 59 is a resin portion formed by insert molding with the metal plate 55 and covers both surfaces of the movable contact plate 51 and both surfaces of the movable contact plate 52. In this embodiment, the coupling member 59 is made of polyacetal resin, polybutylene terephthalate, or the like. The coupling member (resin portion) includes a connecting portion 591 that straddles the movable contact plate 51 and the movable contact plate 52, and a connecting portion 5.
91 to project the protrusion 592 toward the proximal end so as to partially cover the folded portion 550 of the movable contact plate 51, and to partially cover the folded portion 550 of the movable contact plate 52 from the connecting portion 591. And a protrusion 593 protruding toward the base end side. Further, the coupling member (resin portion) includes a protrusion 594 that protrudes toward the distal end side so as to partially cover the single portion 552 of the movable contact plate 51 from the connecting portion 591, and the movable contact plate 52 from the connecting portion 591. And a protrusion 595 protruding toward the distal end side so as to partially cover the single portion 552. Further, a groove 596 extending in the thickness direction is formed on the side surface of the connecting portion 591. In addition, an opening that opens in the thickness direction of the folded portion 550 is formed in a portion that overlaps the folded portion 550 of the coupling member 59 on both sides in the thickness direction. More specifically, the protrusion 592 has openings 597 that open on both sides of the folded portion 550 in the thickness direction, and the protrusion 592 also has both sides of the folded portion 550 in the thickness direction.

FIG. It is explanatory drawing which expands and shows the terminal parts 510 and 520. FIG. FIG. 5 is an explanatory view of the intermediate product after the coupling member 59 is provided on the metal plate 55 shown in FIG. 4, and FIGS. 5 (a) and 5 (b) are a perspective view and a plan view of the intermediate product. is there. FIGS. 6A and 6B are explanatory views schematically showing how the coupling member 59 shown in FIG. 5 is formed by insert molding. FIGS. 6A and 6B are explanatory views inside the mold, and openings 597 and 598. It is explanatory drawing of.

  In order to manufacture the switch member 50 described with reference to FIG. 3, a metal plate 55 having a certain thickness is partially folded and then pressed, and punched as shown in FIG. 4. At this time, the portion constituting the movable contact plate 51 and the portion constituting the movable contact plate 52 are connected by the connecting plate portions 57 and 58. Further, in the end portion of the folded portion 550 opposite to the single portion 552, the side portion of the bent portion 555 is obliquely cut, and the width of the bent portion 555 is narrower than the width of the portion adjacent to the bent portion 555. To do. In the folded portion 550, a through hole 553 is formed, and a hole 556 that penetrates the folded portion 550 is formed closer to the single portion 552 than the through hole 553. Further, a through hole 554 is formed on the tip side of the single portion 552.

  Next, the metal plate 55 is set in a mold and insert molding is performed to form a coupling member 59 (resin portion) as shown in FIG. At that time, as shown in FIG. 6A, the pins 93 and 94 of the molds 91 and 92 are aligned with the hole 556 of the metal plate 55, and the pin 93 is fitted into the hole 556. A hole 556 is formed in a portion of the metal plate 55 where the coupling member 59 (resin portion) is provided, and the coupling member 59 (resin portion) has an opening communicating with the hole 556 as shown in FIG. The parts 597 and 598 are formed.

  Here, the pin 93 is a stepped pin, and the pin 94 has a slightly larger diameter than the hole 556. For this reason, since the folded portion 550 of the metal plate 55 is pushed from both sides by the pins 93 and 94, the folded portion 550 does not open until the insert molding is completed. As a result of adopting this configuration, the openings 597 and 598 have larger inner diameters than the holes 556 as shown in FIG. For this reason, in the opening parts 597 and 598, the part corresponding to the edge of the hole 556 is exposed in the folded part 550.

When positioning the metal plate 55 inside the molds 91 and 92, the metal plate 55 may be positioned at the outer edge of the metal plate 55. Further, when insert molding is performed, in order to prevent the folded portion 550 from opening, a configuration in which the pins 93 and 94 press the folded portion 550 from both sides without forming the hole 556 may be employed. If it is sufficient to prevent the folded portion 550 from opening more than a certain amount, the pins 93 and 94 and the folded portion 550 may be opposed to each other via a gap. In this case, the coupling member 59 (resin In the portion), the folded portion 550 is not exposed at the bottom of the opening formed by the pins 93 and 94.

  Next, after attaching the rivet-shaped contacts 511 and 521 shown in FIG. 3 to the through hole 554 of the metal plate 55 by caulking or the like, the switch plate 50 is completed by removing the connecting plate portions 57 and 58. To do. At that time, since the movable contact plates 51 and 52 (two metal plates 55) are coupled by the connecting portion 591, the process of attaching the contacts 511 and 521 can be performed efficiently.

  When the switch member 50 is incorporated into the switch device 1 shown in FIG. 1, the first case 11 is used as a holding member that holds the switch member 50. At that time, the first case 11 holds the folded portion 550 of the switch member 50. More specifically, the first case 11 holds the coupling member 59 of the switch member 50. When electrical connection to the switch member 50 is performed, the connector 60 is coupled to the connection terminal portions 510 and 520 of the movable contact plates 51 and 52 of the switch member 50.

(Main effects of this form)
As described above, in the switch member 50 according to the present embodiment, the movable contact plate 51 has one metal plate 55 that is partially folded, and the connection terminal portion 510 is formed by the folded portion 550 of the metal plate 55. The elastic plate part 512 is comprised by the single part 552 of the metal plate 55 comprised. Similarly to the movable contact plate 51, the movable contact plate 52 has a single metal plate 55 that is partially folded, and the connection terminal portion 520 is configured by the folded portion 550 of the metal plate 55. The elastic plate portion 522 is constituted by the single portion 552 of the 55. For this reason, even when the metal plate 55 having a constant thickness is used, the elastic plate portions 512 and 522 having appropriate elasticity and the connection terminal portions 510 and 520 having high strength can be formed. Further, since the connection terminal portions 510 and 520 have high strength, the connection terminal portions 510 and 520 can be used for coupling with the connector 60. Further, even when lead wires are connected to the connection terminal portions 510 and 520 instead of the connector 60, the connection terminal portions 510 and 520 are not easily deformed.

  Further, the metal plate 55 is folded so that one end portion in the longitudinal direction faces the other end portion. For this reason, compared with the structure etc. which folded the metal plate 55 in the width direction, manufacture of the switch member 50 is easy. Further, since the end portion of the connection terminal portion 520 is composed of a bent portion 555 in which the two outer portions of the folded portion 550 are connected, burrs, edges, and the like are unlikely to occur. Therefore, when the connector 60 is coupled to the connection terminal portions 510 and 520, catching or the like hardly occurs.

  Further, in the folded portion 550, the width of the bent portion 555 which is bent at the end portion is narrow at the end portion on the opposite side to the elastic plate portions 512 and 522 (end portion on the connection terminal portions 510 and 520 side). Therefore, burrs or the like hardly occur at both ends of the bent portion 555. Therefore, when the connector 60 is coupled to the connection terminal portions 510 and 520, catching or the like hardly occurs.

  In addition, the switch member 50 includes a coupling member 59 that couples portions of the metal plate 55 that overlap each other in the folded portion 550. Moreover, the coupling member 59 is provided at the end of the folded portion 550 on the elastic plate portions 512 and 522 side. For this reason, it can prevent reliably that the folding part 550 opens. In addition, the connecting terminal portions 510 and 520 having a sufficiently long dimension can be provided in the folded portion 550 as compared with the case where the coupling member 59 is provided in the middle portion of the folded portion 550.

The coupling member 59 is a resin portion formed by insert molding with the metal plate 55, and couples the two movable contact plates 51 and 52 (two metal plates 55). For this reason, the movable contact plates 51 and 52 can be handled as an integrated switch member 50. Further, the positional accuracy between the movable contact plates 51 and 52 (two metal plates 55) can be improved. Here, a hole 556 for positioning in the mold is formed in a portion of the metal plate 55 where the resin portion (coupling member 59) is provided, and an opening 597 connected to the hole 556 is formed in the resin portion. 598 is formed. Therefore, as described with reference to FIG. 6, the metal plate can be positioned in the molds 91 and 92.
Further, when the switch member 50 is incorporated into the switch device 1, the first case 11 (holding member) holds and fixes the folded portion 550 of the switch member 50. In particular, the first case 11 (holding member) holds and fixes the coupling member 59 of the switch member 50. For this reason, the first case 11 can reliably hold the switch member 50.

(Another embodiment)
FIG. 7 is an explanatory diagram of another switch member 50 to which the present invention is applied. In the above embodiment, the folded portion 550 is double, but the folded portion 550 may be triple as shown in FIG. In this case, the end portion 559 of the metal plate 55 is preferably located inside the folded portion 550. According to such a configuration, the end portion of the connection terminal portion 520 is formed of the bent portion 555 in which the two outer portions of the folded portion 550 are connected, so that burrs, edges, and the like are hardly generated at the end portion of the connection terminal portion 520. .
